In February 2017 Acacia announced the maiden NI 43-101 compliant Inferred Mineral Resource Estimate (MRE) on the Liranda Corridor, within its West Kenya Project. The Inferred MRE of 3.46 million tonnes at 12.1 grams per tonne for 1.31 million ounces is primarily located on three main zones of mineralisation at the Acacia prospect.
The gold mineralisation at Acacia is associated with shear zones ranging in width from 0.5 metres to 10 metres (averaging approximately 3 metres true width dependent on the zone), hosted by a mafic volcanic sequence. The strike lengths of the explored sections of the main mineralised zones at Acacia vary between 200m and 600m and the resource is currently defined down to a vertical depth of 750m with the structures open down plunge.
In addition, we have identified mineralised zones on the Bushiangala prospect, approximately one kilometre away from the Acacia prospect, but at this stage this material remains unclassified due to drill density and the need to further understand the controls on the mineralisation and its continuity. Recent results from the Bushiangala prospect include, 7m @ 17.6g/t Au, 3m @ 6.88g/t Au and 4m @ 9.99g/t from step-out holes.
Based on the work undertaken to date, the current scale of the mineralisation is between 0.60Mt and 1.50Mt at a grade between 6.0g/t Au and 10.0g/t Au, for a metal target of between 190,000 ounces and 290,000 ounces of contained gold. A key element of the 2017 drilling programmes at Bushiangala is to both move this existing target mineralisation into the Inferred Resource category and to expand the scale of the targeted mineralisation.
The total drilling on Liranda Corridor targets since 2014 amounts to 44 Reverse Circulation holes for 4,438 metres and 132 diamond core holes for 64,700 metres.
